What Causes an Electrical Burning Smell in a NJ Home?

A burning smell in your home should never be ignored, particularly when you can't identify an obvious source such as cooking or a space heater.

An electrical burning odor may indicate overheating wiring, a damaged electrical component, a loose connection, or another electrical problem. Because electrical issues can potentially lead to fires, it's important to take the smell seriously.

Why Does Electrical Wiring Smell Like It's Burning?

Electrical components can produce heat during normal operation, but excessive heat can damage insulation and other materials.

A burning or melted-plastic smell may occur when wiring, an outlet, switch, power strip, electrical appliance, or another component overheats.

A loose electrical connection can also create excess heat. Because wiring and connections may be located inside walls, you may not be able to see the source of the problem.

Check for an Obvious Source

If you notice a burning smell, first consider whether there is an obvious non-electrical source. If the smell appears to be coming from an electrical outlet, switch, appliance, electrical panel, or another electrical component, take it seriously.

Do not continue using a device or outlet that appears to be overheating or damaged.

If you see smoke or an active fire, leave the home and call 911 from a safe location.

Warning Signs of an Electrical Problem

A burning smell is particularly concerning when it occurs alongside other electrical warning signs.

These can include:

• An outlet or switch that feels hot

• Discoloration around an outlet or switch

• Melted or damaged plastic

• Buzzing or crackling sounds

• Flickering lights

• Repeated circuit breaker trips

• Sparks

• Smoke

You don't need to experience multiple warning signs before contacting an electrician. A persistent unexplained burning odor is reason enough to have the electrical system evaluated.

Don't Ignore a Burning Smell Just Because Everything Still Works

Electrical problems don't necessarily cause an immediate loss of power. An outlet can continue working even when there is an issue with its connections or surrounding wiring.

Likewise, a circuit breaker doesn't necessarily trip every time an electrical component is overheating.

If you smell burning but your lights and outlets are still functioning normally, that doesn't mean the electrical system is safe to ignore.

What Should You Do If You Smell Burning?

If you suspect an electrical source, stop using the affected outlet or device. If you can safely identify and disconnect a portable appliance without touching anything hot, damaged, sparking, or otherwise unsafe, do so.

Don't open outlets, switches, or the electrical panel yourself to investigate the source. Electrical components can remain energized and should be evaluated by a qualified professional.

If there is smoke, fire, or an immediate danger, leave the home and call 911.
